碳限额约束下考虑政府补贴和消费者低碳偏好的混合渠道供应链决策与协调

Decision and coordination of hybrid channel supply chain with consumers'low carbon preference and government subsidies under the carbon cap

在碳限额政策下,针对消费者具有低碳偏好以及制造商网络直销渠道与零售商传统销售渠道销售价格存在差异,通过分别建立政府实施不同碳减排补贴模式的混合渠道供应链碳减排技术投入模型,研究混合渠道供应链的销售及碳减排决策问题.研究结果表明:无论采取何种补贴模式,两部定价契约都可以实现混合渠道供应链系统协调;当满足一定条件时,与无碳约束相比,碳限额起作用情形下碳减排率和混合渠道总市场需求量更高;无论采取何种补贴策略,碳减排率是碳限额额度的减函数,利润是其增函数,市场需求与其成U型关系;碳减排率和直销渠道市场需求量是渠道竞争强度的减函数,而传统渠道需求量和利润与其成U型关系;碳减排率、市场需求量以及利润都是政府补贴和消费者低碳偏好的增函数.

Considering the difference of hybrid channel sales prices and consumers'low carbon preference under carbon cap constraint,the models of carbon reduction technology innovation investment on hybrid channel supply chain are established under the government different subsidies for carbon emission reduction,and the sales and decision of carbon emission reduction of hybrid channel supply chain are studied.The results show that no matter which subsidy mode is adopted,the hybrid channel supply chain is able to be coordinated with two part tariff contract.When a certain condition being met,the carbon emission reduction rate and total market demand of hybrid channel supply chain are higher under carbon cap compared to carbon-free constraint.No matter what kind of subsidy mode is adopted,the carbon emission reduction rate is a decreasing function of carbon quota,while the profit is its increasing function,and its relationship with the market demand follows the U-shaped pattern.The carbon emission reduction rate and direct marketing channel market demand is the decreasing function of channel competition intensity,while the traditional channel demand and profit present the U type relationship.The carbon emission reduction rate,market demand and profit are the increasing function of government subsidy and consumers'low carbon preference.
